Map Editor
Anyone who is having problems with the map editor please check these first before replying:
1) Do you have the latest version of DirectX?
2) Does dxdiag report any errors? Is 3D acceleration enabled?
3) Do you have your latest video drivers?
If these are all OK, please describe your problem and post your dxdiag report (just the system info and the part related to your video device will be fine)
